---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Type: Closed dynamic Driver unit: 6mm diameter Frequency response: 20-20,000Hz Power supply: Built-in rechargeable lithium-ion battery Usage time: Main unit/Continuous playback approx. 6.5 hours, Continuous standby approx. 70 hours; Charging case approx. 2 hours; Charging case/Charges the main unit approximately twice Weight: Main unit approx. 3.3g x 2, Charging case approx. 35g Multi-pairing: Up to 4 devices
